I would like to make the following modifications to the existing Odoo addon

There's module A (main addon) with ModuleA class, which has _get_information method

There is a module B with ModuleA class, inheriting from main ModuleA class (with _name parameter), overriding _get_information method, and calling parent _get_information method with super(). _get_information within it's own _get_information method

I created module C with ModuleA class, which inherits Module B's ModuleA class and overrides it's _get_information method, but for some reason module B's _get_information method is used, not mine

How this should be done right?
